Android: Not rendering first slide.

I'v made a basic rn app and added react-native-swiper. When i add a new item to the array im rendering slides from the first slide will not show on android. It works fine on iOS. It allso works fine if there are atleast 2 elements initialy in the array.

index.android.js

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TouchableOpacity
} from 'react-native';
import Swiper from 'react-native-swiper'
class SwiperTest extends Component {
  constructor(props) {
      super(props)
      this.state = {slides: []}
  }

  renderAttachments() {
    return this.state.slides.map((slide, index) => {
      return (
        <View style={[styles.slide1]} key= { index }>
          <Text>{ "Slide " + index }</Text>
        </View>
      );
    });
  }

  onPress() {
    this.setState({slides: this.state.slides.concat("Slide")})
  }


  render() {
    return (
      <View>
        <TouchableOpacity onPress = {this.onPress.bind(this)}><Text >Add slide!</Text></TouchableOpacity>
      <Swiper
        style={styles.wrapper}
        showsButtons={true} loop={false}
        dot={<View style={{backgroundColor:'rgba(0,0,0,.2)', width: 5, height: 5,borderRadius: 4, marginLeft: 3, marginRight: 3, marginTop: 3, marginBottom: 30,}} />}
        activeDot={<View style={{backgroundColor: '#000', width: 8, height: 8, borderRadius: 4, marginLeft: 3, marginRight: 3, marginTop: 3, marginBottom: 30,}} />}
      >
       {this.renderAttachments()}
      </Swiper>
      </View>
    )
  }
}

var styles = StyleSheet.create({
  wrapper: {
  },
  slide1: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#9DD6EB',
  },
  slide2: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#97CAE5',
  },
  slide3: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#92BBD9',
  },
  text: {
    color: '#fff',
    fontSize: 30,
    fontWeight: 'bold',
  }
})

AppRegistry.registerComponent('SwiperTest', () => SwiperTest);

package.json

"react": "15.2.1",
    "react-native": "0.29.1",
    "react-native-swiper": "^1.4.6"

Start by running the provided index.android.js example with react-native 0.29.1 and react-native-swiper 1.4.6, then add the first slide after mounting. Compare Android behavior with iOS and trace how the Swiper handles its children when the initial array is empty; done means the first dynamically added slide renders on Android without breaking the existing behavior.
